Paper books > Ebooks.
I’ve never really been able to focus when reading lengthy novels or even textbooks online. After prolonged periods my eyes just hurt from staring at the screen and zooming in/out because of little font annoys me. I also like making notes in margins and highlighting quotes and being able to read anywhere without worrying about battery life and/or wifi. Also people are less likely to steal my book than they are my iPad.
Reading Ebooks are not all bad like you can search specific things like words or chapters more quickly, I guess. But I just like touching books, putting them on the shelf and manually flipping pages. It’s easier for me and it’s just a different experience than Ebooks. I just like paper books.
